They cycled across the border from Tumen, in the northeast of China, and visited Nanyang City in North Korea before returning to China the same day.

The group visited Nanyang train station, the Korean War Hero Martyrs Monument, a portrait of Kim Il Sung, The Tower of Immortality, attended a show and sampled local snacks from a small farm market behind Nanyang International Hotel.

That hotel is where Kim Il Sung reportedly met Zhou Baozhong, a famous Chinese World War II general.

The first trip took a little more than three hours.

Zhao Xin, one of the cyclists on the trip, told Xinhua, China's state news agency, "In North Korea, the food was pollution-free: vegetables, fish, eggs, they all tasted not bad. We had no worries eating there."
